Abstract

Objectives: Comment on the histological distribution and the value of some characterisrics on chest computed tomography in predicting the risk of lung cancer. Subjects and methods: Descriptive and prospective study on 116 patients with peripheral solitary tumor-like lesions who were diagnosed and treated by Video-assisted-thoracoscopic surgery at the Department of Thoracic Surgery - Pham Ngoc Thach Hospital, from 11/2011 to July 2014. Results: The mean age was 57.1 ± 12.3, the male/female ratio was 1.3/1. Distribution of patients according to histopathological results include: cancer accounted for 41.4%, of which adenocarcinoma accounted for mainly (97.9%); Benign tumors accounted for 58.6%, of which: tuberculosis and chronic pneumonia accounted for mainly (69.4% and 23.6%). Analysis of the relationship between some features on chest CT with histopathology showed: lesions in the middle lobe of the right lung, lobulated margin or irregular with many spiculation, has a higher rate of lung cancer (p < 0.01), while lesions of 2cm or less in size, sharp and smooth margins have a higher rate of benign tumors (p < 0.005); The rate of lung cancer increased escallatelly with the lesion size. Conclusion: Peripheral solitary tumor-like lesions often have histological of  adenocarcinoma lung cancer (rate 40.5%) or tuberculosis (rate 43.1%). The location, size and characteristics of the tumor margin on the chest CT scan have good value in predicting the risk of lung cancer.
